The Alloy-Theoretic Automated Toolkit (ATAT) is a generic name that refers to a collection of alloy theory tools developed by A. van de Walle in collaboration with other research groups:

• MIT Ab-initio Phase Stability code (MAPS) constructs cluster expansions from first-principles (Gerd Ceder)

• Eazy Monte Carlo Code performs Monte Carlo simulation of lattice models in order to compute thermodynamic properties of alloys starting from a cluster expansion (Mark Asta)

• Constituent Strain Extension code (Alex Zunger)
